I know this is a silly question but are you sure the stand braces weren't up against the wheel or pulley somewhere? I did this once. You have to make sure the stand isn't rubbing anything.
Ok im a *******, new tire has a taller profile and the stand doesnt lift it off the ground completely.
Thanks luigi. I was only joking around but I do appreciate that rep point[up] I give you one backCongrats Lesley
